You have a raidz1 pool with one or MORE devices that seem to have left the stage. I suspect more than one. I can only guess what you see from "camcontrol devlist" as well as data from "gpart show -l" where we would see the partition data along with and GPT labels. If in fact you used GPT scheme. You have a list of devices that all say "p1" there and so I guess you made some sort of a partition table. ZFS does not need that but it can be nice to have. In any case, it really does look like you have _more_ than one failure in there somewhere and only dmesg and some separate tests on each device would reveal the truth. -- Dennis Clarke RISC-V/SPARC/PPC/ARM/CISC UNIX and Linux spokenhome | help
